  拉刀切削負荷的計算
  Calculation of pulling force
  預想負荷(kgf) =切削寬度(mm)x1刃的切深(mm)x單位面積切削阻力(kgf/mm²) x同時切削刃數安全負荷(kgf) = 1.8x預想負荷(kgf)
  預想負荷是拉刀在普通狀態下加工時所必需的切削力。 隨著拉刀刀刃的不斷磨損.就需要逐斬加大切削力, 但加大到一定程度后拉刀會破損 , 或者因拉床的維護狀態不良而在切削中停機。 安全負荷就是指為了防止出現上述情況的允許切削力 。
  Calculation of pulling force Expected force(Kgf) =Cutting width x Cutting depth/1 tooth(mm) x specific cutting resistance(kgf/mm²) x number of simultaneous Safety load(kgf)=1.8 x Expected force(kgf).
  Expected force means that necessary cutting force for broaching under norma1 condition. Safety load is permitted cutting force.
  拉刀全長和拉床行程的關系
  Broach cutter length and machines stroke
  拉刀的長度要受到拉床的行程及夾具的限制 。
  拉刀刃長+后部柄長(MAX)= (最大行程) - (工件切削長度)
  所需行程=刃長+工件切削長度+后柄長度<拉床最大行程
  由于產品在不斷的改進中,樣本技術參數如有改動,恕不另行通知。
  Broach cutter length and machines stroke Broach length is limited by machine stroke and jig/fixture
  Broach cutter teeth length+length of rear shank=(Max stroke)-(cutting length)
  Necessary stroke=Teeth length+length of rear shank+Broaching length<broaching machine stroke(max)
